The Health Planet Walk app is a free pedometer designed for iPhone users, utilizing the same algorithm as Tanita's pedometers. It provides a clear visual representation of daily steps with pie charts and numerical data, making it easy to track progress toward goals. Users can view additional metrics such as calories burned, walking time, and distance traveled. The app allows for tracking both daily and weekly step goals, with graphs to visualize performance over time.

To enhance health management, the Health Planet Walk app can integrate with the Health Planet service, enabling users to store data securely on the cloud, even during device changes. Registration with the Health Planet system is necessary to access features like weight and blood pressure tracking, assisting users with their fitness and diet plans. The app requires specific privacy settings to function properly, ensuring accurate step counting and notifications.
